I bought the SQL Developer Bundle last week. Support for SQL 2000 was working fine before and was critical in my decision to purchase the product. SQL Compare is now useless to me without support for SQL 2000. Waiting a couple of weeks for fix seems unreasonable. Does RedGate not offer hot fixes for bugs they introduce? Can I uninstall the product and install a previous version?

I am running version 10.0.0.160 without any problems but do see problems with latest. Could you post this older version for download? I only saw through 9.5 of SQL compare as available from older versions download.

Just to reiterate, "Specified Cast is not valid" is a generic exception and therefore will never be eradicated. First, yes, it could be a programming mistake. But more commonly, it's inconsistency in the metadata describing the database schema.

I'd recommend emailing support at red-gate.com and open a support case.
